ALFRED BERNEY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE GLOBE COMPANY,OF HARTFORD, CONNECTICUT.

SPARK ARRESTER AND CONSUMER.

SPECIFICATION forming part of Letters Patent No. 240,500, dated April26, 1881.

' Application filed March 14, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALFRED BERNEY, a citizen of the United States,residing at the city of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inSpark-Consuiners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompa= nying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to mechanism by which sparks are returned to thefire-box or other receptacles.

The invention consists in the construction and arrangement of parts, aswill be more fully described hereinafter, reference being had to theaccompanying drawings and the letters of reference marked thereon.

In the accompanying drawings, Figure 1 is a longitudinal section of alocomotive-boiler 2 5 with my improvements attached. Fig. 2 is a portionof an inside smoke-stack, with vertical section of my improved cone,showing a plan of securing it in position. Fig. 3 is a plan View of thesame, partly in section. Fig. 4 is 0 a view of a quarter-section of coneand collar. Fig. 5 is a vertical section of a deflecting and heatinghood attached to a portion of a flueblast. Fig. 6 is a front View of adeflecting and heating hood.

In drawings, Fig. 1, A represents a locomotive-boiler, having the usualfurnace, B, tubes C, smoke-stack D, draft-pipe E, and exhaustpipe F,connecting'pipe Gr, return-fines H, 'deflector and heater 'I, steam-pipeK, saddle L,

40 stack M, inner barrel, N, deflecting stackfiange 0, insidepipe-flange, P, and cone Q.

The annular flange O is riveted or otherwise secured to the interior ofthe stack, close to the pendent tubes q of the cone, to assist in de- 5flectin g the sparks, &c., into the annular space between the inner andouter barrels of the stack.

In drawings, Figs. 2, 3, and 4, A represents the cone, which is castpreferably in five partsthe top and quarter sections, as shown in Fig.

4. These are bolted together, as shown at a,

by flanges and bolts. The heating-deflector I is cast in the shape shownin Figs. 5 and 6. The holes can be used to allow the steam and air-topass through or with a perforated plate, R. They can be filled up with anon-conducting material placed in the cavity S, which can be also usedto heat air, or filled with asbestus or some similar material, toprevent the burning out of the deflector. The deflector is provided withprongs F, which are intended to keep pieces of wood from closing orchoking the passage, as in this way it would bealmost impossible,'whenusing wood as fuel, to close them up. The cavity is so formed as to holdthe air and steam to heat it before being deflected into the fire.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- 1. In a spark-arrester, a cone, Q, consisting ofradial vertically-cut sections provided with tubes q, arrangedsubstantially as shown and described.

2. In a spark-arrester, the cone Q, construct- 7 5 ed as described, incombination with the an. nular space of the chimney, the saddle-plate L,connecting-pipe Gr, return-fines H, and a steam-jet, all arranged foroperation substantially as specified. 8o

3. In spark-arrester, the combination of return-flues H with adeflector, I, having perforations, and a perforated plate, R, and prongsT, substantially as and for the purpose specifled.

4. In a spark-arrester, the cone Q, made in vertical sections boltedtogether, in combination with the annular flange O, secured to the stackfor the purpose of deflecting the sparks, substantially as described.

5. The spark arrester and consumer herein described, consisting of thestack M, cone Q, deflecting-flange O, saddle L, connecting-pipe Gr,steam-jet K, return-fines H, and hood I, all constructed and arranged asshown, and for 5 the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED BERNEY.
